s claims. (o1. afi-'73) Y v l overthefront part lof the radiator guard by a plurality of my improved clip fasteners. .l

This invention relatesto an improved construction of clip `fastener particularlyl Iadapted fordetachably securing a fabric or pliable'covering over the front of an 'automobile radiator or guard grill thereof forVthe purpose ofholding said fabric or coveringin operative position on the grill.

The main objectof the invention is .to provide a clip fastener of the character described, which 10 will be simple and inexpensive to make. and

which will be so constructed as kto adapt it for use on ,radiator guard grills of different sizes and` lwhen attached in place will have a sufliciently large base so as to substantially prevent lateral displacement of the clip fastener.

Another object of. the invention is to providev With the foregoing and other objects in view which will appear as the rdescription proceeds," the invention. consists in certain novel features of construction, arrangement and combination of parts hereinafter more fully described, illustrated in the accompanying drawing, land particularly pointed out in the appended claims, it

vi being understood that various lchanges in the form, proportion, size and minor details of the structure may be made without departing fromk the spirit or sacrificing any of the advantages of the invention.

For the purpose of facilitating'an understanding of my invention,l I have illustrated in the accompanying drawing Apreferred embodiments y thereof, from aninspection of which, when considered in connection with the following description,l my invention, its mode of construction, as-

sembly and operation, and many of its advan-V tages should be readily understood and appreciated.

Referring to the drawing characters of reference are employed to indicate several gures of the drawing:

Fig. 1 is a diagrammatic front elevational view of the frontof an automobile, illustrating a ra- 5;;v diator cover applied and securely held in place in which the same corresponding or similar parts throughout the Fig. 2 is an enlarged elevational view of the fastener in Iposition for securing a cover to the bars fof a grill guard of an automobile radiator front.

Fig'. 4 is a sectional View taken substantially` on the line 4-4 of Fig. 2.

Fig. 5 isa sectional view taken substantially on the line 5 5 ofv Fig. 3.- v t y, Fig. 6" is a-'modied form of my improved fastener showing the hook member detachably secured-to the coil spring. f

Fig'. 7 is al still further'modied form of my clip lfastener showing thehook member provided with a hook at its yfree end and a second'hook intermediate the endsfthereof.v

It is customary to' protect the. front of an f I y in the summer may be in the form of' a wire screen fabric to preventv insects or the like' from clogging .the front ofthe radiator. In the manufacture of -automobiles at the present time there is provided a grill guard for the radiator, which comprises Va series of either vertically or horizontally spaced bars of substantially U-shaped formation in cross section, said bars being spaced from eachother at varying distances, depending upon vthe make of the. car. The fastener heretofore used,qand which is disclosed in my Patent vNo.l 2,076,7`26,'issued-April 13, 1937 comprised a kconical spring, the largest convolution of which is approximately one inch in diameter, this convolution forming vthe base for the fastener when the sameisin operative position. I` have vfound that these clips worked satisfactorilyv when `the distance between the grill bars was lessgthan an' inch, however, when theL o fr having an elongated loop which may be formed from the terminal of the largest convolution, which loopmay be of a length of substantially three inches, with the result that the over-all dimensions of the conical spring will be substantially the same as those heretofore used.

Referring to the drawing more specifically by characters of reference, the character l0 designates generally a stem or hook member formed of wire, bent at one end to provide a suitable hook H for engaging a grill bar or the like of a radiator guard, or bars or tubes of a radiator.

The opposite end of said stem I0 is bent downs wardly upon itself to form a head or linger hold l2, from which portion it is bent to pro-i duce a series of convolutions to produce a conthe form of an elongated loop I 5 as'shownin Fig. 5, the length of which is approximately two and one-half to three times that of the diameter of the largest-convolution I3.

The extreme free end I6 of the wire may be secured to one sidel of the loop i5 by means of a sheet metalclip i? as shown in Fig. 5 or in some other suitable and well known manner. f

By reason of the construction hereinabove described, it will be apparent that the clip fastener may be employed for usev with radiator grill guards, the bars of which may be spaced apart a distance anywhere from one-quarter inch up to approximately three inches, thus rendering the devicel capable of use with radiator grill guards of substantially all'makes of cars on` the market at the present time Without necessitating the manufacture of clip fastenersy of varying sizes, asthis one size of fastener will t substan It will also be noted that by reav tially all cars. son of the large area which will be covered by the loop l5, a substantially rigid base will be provided for the fastener, thereby preventing the same from lateral displacement in use. It will also be noted that in providing the end elongated loop, the sizeof the fastener will be comparative-y in the cover i8, and the hook member passed inwardly between a pair of bars 20 of the grill guard, to a depth which will enable the hook end I I to be hooked to the rear side of-a bar as shown in Fig, 4.

The spring Vunder its compressed condition will yieldingly bind the hook memberv to a bar and clamp the portion of the cover engaged against the front side of the bar -of the radiator front. Any number of clips of the type illustrated sufficient to properly hold the cover in placeniay be employed, the said clips being arranged preferably about the margin of the cover and the ap'- proximate locations for the hooking of the bar of the radiator guard or radiator itself. VBy reason of the size of the loop portion l5, it will be readily apparent that a smaller numberof clip fasteners may be employed and also that the edges of the covering maybe more securely fastened in place to the guard grill than would be possible with the fasteners heretofore in use In the modified form lshownin Fig. 6, thestem conically coiled spring3l, the stem 3i) being provided at one end with a hook 32 and its opposite end with a hand hold 33, the latter being formed with a reduced neck portion 34, by means of which the smallest convolution of the conical spring 3l may be detachably assembled to the stem 3B by snapping the said smallest convolution in place over the reduced or neck portion of the hand hold 33.

In the modification shown in Fig. 7, the stem d@ is Aformed integral with the conical spring 4l in the same manner as 4that illustrated and described in` connection With the modifications f shown in Figures l to 5, `except that the stem 4|] islv'provided in additionto the hook 42 at one end thereof with a second hook 43 formed intermediate the ends thereof. The purpose of this 'construction is to enable this modied form of fastener'ft'o be vused upon the grill guards, the depth of the bars of which may vary.

'From the above it will be apparent that there construction and assembly, and many of its advantages should be readily understood from the foregoing without further description and itl should also be manifest that while preferred embodiments of the invention have been shown and described for illustrative purposes, the structural details are nevertheless capable of wide variation within the purview of my invention as defined in' the appended claims.
